Figure 5.

EPSCs in SG neurons evoked by 5 (A), 250 (B) and 2000 (C) Hz transcutaneous sine-wave
stimuli. In A-C, the stimulus intensities were shown above the traces. Lower two records in
A were shown in an expanded time scale. Relative frequencies of large amplitude of EPSCs
evoked by the stimuli at intensities of T5, T250 or T 2000 (D). *P < 0.05, **P < 0.01.
